We have to do our drawing through this PGraphics instead of the typical method, but it really doesn’t change a whole lot in the end. Things to note, after importing the syphon library from step 4, we create a variable “canvas” of type PGraphics. Server = new SyphonServer(this, 'Processing Syphon') Create syhpon server to send frames out. This should add an import command at the top of your source code.ĥ) Add the following both inside and outside your setup function to prepare to send the images: If it isn’t there, you messed up one of the previous steps :(. You should see an INSTALL.txt and a folder simply called Syphon.ģ) Drag the folder called Syphon into your libraries folder in your Processing folder, which is typically located at /Users/your_name/Documents/Processing/librariesĤ) Restart processing if it was running, and then go to Sketch>Import Library>Syphon.

Full Source code is at the bottom.ġ) Download Syphon for Processing through this link: Ģ) Extract the folder from the zip, and look inside. I apologize for the bad picture quality.Syphon allows the user to directly send the output of a Processing Sketch into MadMapper, or equivalent program. This very short video shows the mapped video with the LED pixel tape bars alongside the projection surfaces. Unfortunately, I have only a few pictures and videos from the event. I guess the takeaway is that you can essentially combine anything with anything as long as it all speaks MIDI. Of course I could have done this using a virtual PC on the Mac but the load would have been a bit much for one physical machine. The reason this was done on two computers rather than on one is the fact that the laser and led control software I used are only available on Windows. In these Ableton clips, MIDI chords were used to trigger, for example, clips or photos on the two video projectors simultaneously with a laser pattern, a LED pixel tape pattern and a DMXIS preset. Everything was controlled using MIDI clips in Ableton. The MIDI signal was sent from the Mac to the PC over ethernet (using rtpMIDI on the Windows machine). video projected onto three book cases (mapped with another instance of Arkaos Grand VJ XT running on the same Windows PC).Įverything was tied together with MIDI. LED pixel tape bars (triggered by Jinx! - LED Matrix Control software running on the same Windows PC) and a laser projector (triggered by Pangolin Quickshow running on a Windows PC) video projected onto a styrofoam cube (mapped with Arkaos Grand VJ XT running on the same Mac) regular lighting fixtures using DMXIS (running on the same Mac) This involved using Ableton on a Mac to trigger: I have used a similar - and possibly even more ambitious - setup recently.
